JOSEPH H. PILKINGTON, OF WATERBURY, CONNECTICUT.

SNAP-FASTENER.

Application filed March 31, 1919. Serial No. 286,535.

To all whom it may concern: 7

Be it known that I, JOSEPH H. PILKING- 'ION, a citizen of the UnitedStates, and resident of Waterbury, in the county of New Haven and Stateof Connecticut, have invented certain new and useful Improvements inSnap-Fasteners, of which the following is a specification.

This invention relates to new and useful improvements in snap fastenerssuch as com prise a button member and a socket member each adapted to beseparately attached to two pieces of fabric and detachably connected forsecuring the two parts together.

My present invention has for its object to produce a more durablefastener of the above class, than any now upon the market and to designthe same so that it can be made .up in various sizes and used fordifferent purposes as for instance upon garments of different sorts aswell as bags, canvas and vehicle curtams, further to design the clasp sothat the same may be formed from sheet metal stampings ready for quickassembling and attachment to the parts upon which it is to be used.

Further objects and advantages of the invention will appear inthe'following specification and novel features of this device will befurther and particularly pointed out in the appended claims, and uponthe accompanying drawings, forming a part of this specification, will benoted similar refer ence characters to indicate the corresponding partsthroughout the several figures of which:

Figure 1 shows a perspective view of the two members of my claspseparately attached to a piece of fabric.

Fig. 2 shows a central vertical section through both the button andsocket members of the fastener as they would appear attached to the twoparts of a garment, and in the act of being disconnected one from theother.

Fig. 3 is a side view of the button member alone.

Fig. 4: represents a bottom View of the button member as shown in Fig.3.

Fig. 5 shows a detached side View of a small spring employed between thetwo buttons.

Fig. 6 shows a plan view of the sheet metal blank forming the base inwhich the buttons are mounted, and

Fig. 7 shows a perspective view of the two parts that form the socketmember which engages the buttons.

From the foregoing it will be seen that the buttonmember of the fasteneris made up of four pieces while the socket is formed of two pieces,.thatare adapted to be applied to the opposite sides of the material to whichit is to be attached. hese two members maybe attached in any desiredmanner. but I have preferably used integral means adapted to be passedthrough the fabric and bent down upon'the opposite side'to hold them inplace. I

The button member A comprises a sheet metal base that is stamped up toinclude a central elongated opening 8, prongs 9 and two outwardlydisposed tongues 10 which 'arepositioned on the ends and in alinementwith the central opening and between the prongs. The'prongs are laterbent down at a right angle as shown in Fig. 3 to form fastening meansand the tongues are bent in and down upon the base of the buttons tohold them in position.

' I employ two studs or buttons 11 and 12 which are very similar but notexactly alike as will later be explained. Eachof these buttons includesa flanged base 13 whose inner sides are cut away to form the straightsides 14: that fit against each other when the buttons are positioned inthe base. Each of the buttons is also provided with a verticallongitudinal groove 15 which alines and registers with that of theother, when the buttons are positioned to receive the small spring 16that is placed therein and which serves to yieldably hold the upper endportions of the button apart. The tongues 10 are bent over and down uponthe bottom end of the buttons and serve to hold the same in position,but permit of a slight yield to the button as is necessary to allow thesocket B to slip on and 01f of the head of the button. It will be notedthat the buttons 11 and 12 are provided with notches 17 and 18 in theirouter sides, which are positioned in alinement with each other, leavinga contracted neck portion around which the socket member is positionedwhen attached. The notch 17 is provided with a shoulder 19 upon its topside tohold that end of the socket member B as indicated in Fig. 2,while the other notch 18 is not so deep and has a rounded outer facedhead portion to permit the socket to slip over when pressure is appliedas will also be understood .side.

The socket member B includes an inner plate having a central hole 21there through with a head 22 formed around the same on the inside. Aseries of slots 23 is formed through the plate to receive the prongs 24upon the outer plate 25 which is also provided with a central hole 26that registers with the hole 21 in the under plate, and the two serve toreceive the heads of the buttons when the socket member is attachedthereto. In the attachment of the socket member to the fabric one plateis placed upon one side of the fabric and the other plate is placed uponthe opposite side in position to have its prongs shoved through thefabric and the slots of the under plate and then bent down as shown inFig. 1 to form a secure attachment of the parts.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is-

1. A snap fastener comprising a button member and a socket member, thebutton member including a base, a pair of buttons mounted in the baseand each including a longitudinal groove and neck and head portion, oneof the heads having a more pronounced shoulder upon its under side thanthe other, and a spring positioned in the grooves to yieldably hold thebuttons apart.

member and a socket member, the buttonmember including a pair of buttonseach having a head and flanged base, a base plate to support the buttonsand having edge portions that are bent over to engage and yieldablysupport the buttons on the base plate.

8. A snap fastener comprising a button member and a socket member, thebutton member including a base plate and a pair of buttons eachincluding a flange that is yieldably supported between two portions ofthe base and having longitudinal grooves, and a spring positioned in thegrooves to yieldably hold the buttons apart.

4. A snap fastener comprising a button member and a socket member, thebutton member including a base plate having a hole therethrough, twobuttons positioned in the hole and having flanges seated against theunder face of the plate, and means engaging the under side of theflanges to hold them against the plate.

5. A snap fastener comprising a button member and a socket member, thebutton iember including a base, a pair of buttons yieldably mounted inthe base and having longitudinal grooves formed in their adja centsides, and a spring positioned in the grooves to yieldably hold thebuttons apart.
